The Manhattan GMAT Live Online course was excellent. Ryan Wessel and David Chong were really good instructors. I raised my GMAT score by 100 points (from 620 to 720) by taking the class. The class was given once a week for 9 weeks.
The most helpful lectures were on the subjects of:
- Sentence correction
- Data sufficiency
- Reading comprehension
The recorded labs offered had some of the most insightful tips and shortcuts I learned throughout all my time studying for the course. The information given in the labs was extremely relevant for test day; the labs taught things such as timing strategy, shortcuts to data sufficiency questions, etc.
